If you remember from about a month ago, a developer brought startup sound customization to iOS with his application iStartupSound. Although this application is not a staple function for iOS users, it is a fun tweak that gives you some unique customization to your iDevice. Vladislav Korotnev (@vladkorotnev) has recently released his second "sequel" to his line of startup applications called iStartupMovie. His new application once again brings a unique feature to the startup genre.

Just as the title says, iStartupMovie allows movie or video clips to play on your device during startup or respring. Whenever you reboot, shutdown and turn on, or even respring your device, whatever clip you have chosen will play before the SpringBoard displays on your device.

The videos files must be in .mov/.m4v format and placed on your device via SSH. Here's the SSH location:

/var/mobile/Library/StartupMovies

To choose what clips play, use the iStartupMovie Manager application that will appear on your SpringBoard after installation.

Note: Since the SpringBoard will not display until the clip is finished playing, a word of advice: keep your clip short and sweet.

Try iStartupMovie out on Cydia (on the BigBoss repo) and post your thoughts here: it is compatible on all iDevices and firmwares (has not been tested on the iOS 5 beta - testing and using on a beta is done at your own risk. Note the consequences and risks of testing software on a beta that has unconfirmed compatibility). It is also free, however the creator is accepting donations if you so desire. Donate to him here.

UPDATED: As you can see from the first photo, it appears that words are overlapping on the status/toolbar. This is due to incompatibility with Ryan Petrich's DietBar. The problem doesn't inhibit use of the application so no worries. I have spoken with Vladislav and he knows of the issue.

When I tried to charge my iPhone
That's what I meant 

Yes, I had the same issue. Whatever battery percentage, and battery state (charging or not) that was on my status bar after the initial respring, stays. I can plug in the cord all day, but the battery percentage, status icon, as well as the "plugged in" sound, all do not change.

After installing this tweak, I was unable to charge my phone at all. I decided to give it a respring to see if that would fix it. After respring, my phone (iPhone 4 on 4.3.3) froze at the passcode screen! I tried rebooting the phone only to have the same thing happen again. In the end, I had to connect via USB and go through iPhone Explorer to delete everything that was installed from iStartupMovie.
